LATHING.

SPECIFICATION forming `pari: of Letters Patent No. 334,603, dated January 19, 1886.

Application filed November 2, 1885. Serial No. 181,570.

To all whom it may concern,.-

Be it known that I, OHAELEs EMERRT- FIELD, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvementsin Lathing, of which the following is a specilication.

The objects of my improvements are to provide a lathing which, while having all the advantages of the so-called combined wooden sheathing and lath, will be cheaper and can with less difficulty be manufacturedthan the same. I attain these objects by the device illustrated in the accompanying drawings, in Which#- Figure l is a perspective view of my iniproved lathing and plastering when applied to the walls or ceilings of a frame house, and Fig. 2 a vertical cross-section through my lathing. In Fig. 3 I show the strips between the lath made in two pieces, each having a groove out on but one edge and having the other edge' straight.

Similar letters refer to similar parts th roughout the several views.

A A are narrow Wooden strips of about one inch thickness or more or less. These strips have a groove, a, cut in their edges of sufficient Width to receive an ordinary lath, B, and a certain amount of mortar, the strips A A, the lath B B, and the grooves a a forniing the facegrooves G to receive the key of the plastering.

The device is applied in the following manner: A strip, A, is horizontally nailed to the Wall, then a lath. B, is set onto the upper groove a of the strip A, a second strip is put onto the lath with its groove fitting over the same, the strip is nailed to the wall, then a lath is inserted again on top of the last strip, and so on. The lathsB are resting with their backs against the straight vertical back wall ofthe grooves a, while the front wall of said grooves, out rabbeted, as shown in Fig. 2, or beveled or rectangular, as shown in Fig. 3, holds the lath in place, and at the same time formsa key for the plastering I). The strips A A being of about the thickness of the common sheathing, and being spaced close together with the lath fitting into the grooves aa, the benets and advantages of a combined sheathing and lath are obtained at (No model.)

much less cost than the articles now manufactured under that name; for in the combined sheathing and lath Where wedge-shaped grooves are cut into the face of the boards in order to form a key'ior the plastering the material thus cut out of Vthe boards is aperfect loss.

Waste strips canbe used to form my strips A A, thus utilizing and making valuable what otherwise would be of little or no value. Further, to cut the key-grooves into the face of the sheathing-boards requires theiuse of expensive and complicated machinery, while in my device the edge grooves can be cut into the strips A A by any ordinary flooring machine, with but the small outlay necessary to adapt the bit to the shape ofthe groove wanted. This is an advantage of great impor-tance, as it will insure the manufacture and use of my device wherever a tlooring-machine is operated. g

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

I. A lathing consisting of the common lath B B and the narrow strips A A, having grooves ct a -cut into their edges of such a shape as to receive and hold the lath BB and to form a key for the plastering, substantially as described and specified.

2. In lathing, the combination of the common lath B B and the narrow strips A A, said strips A A having grooves c a cut in their edges of suicient size and such a shape as to receive the lath B B and enough mortar to form a firm key for the plastering, substantially as described and specied.

3. In lathing, the combination, with the common lath B B, of the narrow strips A A, of suicient thickness as to have grooves a c cut into their edge wide enough to receive the lath B B, and to allow of a mortar-key for the plastering between the face of the lath and the front wall of the groove, substantially as described and specified. Y

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnessesl CHARLES E. MERRIFIELD.
